I spoke too soon. Same error in edison tarballs.  I looked at the code and
I can see an place were rdev could go un assigned. If you fell out of the
for loop without passing any of the if conditions, rdev would be
unassigned.  That must be what is happening in Ubuntu 11.10 x64

Anybody building with Ubuntu 11.10 x64?  This doesn't happen on x32

def set_device(e):
    tmpdir = bb.data.getVar('TMPDIR', e.data, True)
    try:
        os.remove(bb.data.getVar('DEVFILE', e.data, True))
    except:
        pass

    # We look for the volume TMPDIR lives on. To do all disks would make
little
    # sense and not give us any particularly useful data. In theory we
could do
    # something like stick DL_DIR on a different partition and this would
    # throw stats gathering off. The same goes with SSTATE_DIR. However,
let's
    # get the basics in here and work on the cornercases later.

    device=os.stat(tmpdir)
    majordev=os.major(device.st_dev)
    minordev=os.minor(device.st_dev)
    for line in open("/proc/diskstats", "r"):
        if majordev == int(line.split()[0]) and minordev ==
int(line.split()[1]):
           rdev=line.split()[2]
    file = open(bb.data.getVar('DEVFILE', e.data, True), "w")
    file.write(rdev)
    file.close()
